C5 A6 Turn Signal won't Work
 

Hi all, I've been having an issue with the turn signal on my 2000 A6 Avant. The turn signal worked sporadically but slowly got worse and is now almost completely useless. My four ways still work so I don't believe the issue to be the relay. I bought a new turn signal stalk and replaced it following a very useful guide on this forum but the turn signal still doesn't work! I know I installed it properly because I can still get that same flaky response if I fiddle with it. I was certain that the issue was the switch in the stalk so now in at a loss for what the problem could be. Any ideas?
